Lignin
Lignin is practically insoluble (in water) and an extremely strong acidic compound (based on its pKa). Lignin can be found in a number of food items such as evening primrose, carob, sunflower, and corn, which makes lignin a potential biomarker for the consumption of these food products. Lignin is a class of complex organic polymers that form important structural materials in the support tissues of vascular plants and some algae. Lignins are particularly important in the formation of cell walls, especially in wood and bark, because they lend rigidity and do not rot easily. Chemically, lignins are cross-linked phenolic polymers .
Lignin
The most abundant natural aromatic organic polymer found in all vascular plants. Lignin together with cellulose and hemicellulose are the major cell wall components of the fibers of all wood and grass species. Lignin is composed of coniferyl, p-coumaryl, and sinapyl alcohols in varying ratios in different plant species. (From Merck Index, 11th ed) Lignin is a class of complex organic polymers that form key structural materials in the support tissues of most plants.[1] Lignins are particularly important in the formation of cell walls, especially in wood and bark, because they lend rigidity and do not rot easily. Chemically, lignins are polymers made by cross-linking phenolic precursors.[2] Lignin was first mentioned in 1813 by the Swiss botanist A. P. de Candolle, who described it as a fibrous, tasteless material, insoluble in water and alcohol but soluble in weak alkaline solutions, and which can be precipitated from solution using acid.[3] He named the substance "lignine", which is derived from the Latin word lignum,[4] meaning wood. It is one of the most abundant organic polymers on Earth, exceeded only by cellulose and chitin. Lignin constitutes 30\% of terrestrial non-fossil organic carbon[5] on Earth, and 20 to 35\% of the dry mass of wood.[6] Lignin is present in red algae, which suggest that the common ancestor of plants and red algae also synthesised lignin. This finding also suggests that the original function of lignin was structural as it plays this role in the red alga Calliarthron, where it supports joints between calcified segments.[7]

Bicuculline methiodide
C21H20INO6 (509.03353300000003)
Bicuculline methiodide is a potent GABA(A) receptors blocker. Bicuculline methiodide alters membrane properties and firing pattern. Bicuculline methiodide reduces the Apamin-sensitive afterhyperpolarization, while Apamin is a toxin isolated from bee venom to block small conductance Ca2+ -activated K+ channels. Bicuculline methiodide facilitates burst firing via blocking apamin-sensitive Ca2+ -activated K+ current[1].
